“I bought a Jewish sports car. It not only stops on a dime, it picks it up”

American singer, songwriter and novelist Kinky Friedman joked on the Jewish reputation for being tight with money. “Y’know the definition of a Jewish Cadillac? It stops on a dime and picks it up,” Friedman said at New York’s Lone Star Cafe in 1978.

A slightly different version was printed in Totally Tasteless: The Collected Works (so far) of Blanche Knott (1983):

“Did you hear about the new brand of tires—Firestein? They not only stop on a dime, they pick it up.”

“I mean, I’m actually enjoying these gigs, because I know that everything is not riding on it. Me and my agent Cleave are riding in a Cadillac called the Yom Kippur Clipper - it stops on a dime and picks it up.”

22 June 1992, The Daily Telegraph (London, UK), “Riding with the Kinkster Kinky Friedman not only mixes country music and Judaism, he also writes detective novels about himself. Richard Lloyd Parry joined him in his Cadillac,” pg. 13:
Outside, [Kinky Friedman]’s wheels await him - a black, chauffeur-driven 1952 Cadillac saloon, hired specially for his visit, the same model in which Hank Williams died in 1953. The Kinkster embarks, followed by Miss Rita Jo Thompson, a former Miss Texas and his companion on this seven-city tour. “I call it the Yom Kippur Clipper,” Kinky explained, as he has explained to interviewers dozens of times before. “It’s a Jewish Cadillac: it can stop on a dime - and then it picks it up.”
